A small group of gay marriage supporters held a very vocal demonstration in Downtown Honolulu Monday to highlight the high court's examination of same-sex marriage.

"My hope is that they will see that discrimination against homosexuals is an abridgment of your U.S. civil rights," said Jo-Ann Adams, with Hawaii United for Marriage.

In Honolulu, along with other cities across the country, supporters of same-sex marriage gathered to commemorate civil rights changes over the years. They also recognized all the efforts to get the current cases before the Supreme Court.

"We've made it to the Supreme Court and that gives us a chance. The Supreme Court is the only one that can change public policy. We are now before the venue that can change public policy, that's very exciting," exclaimed Adams.

A decision on the measures may not come for months, but legal experts said the two days of arguments by the justices could indicate how the high court could rule.

"Listening to what the justices ask may give a hint about how strongly they are leaning toward really deciding the heart of the matter," said Steve Wermiel, with the American University.

Supporters and opponents may disagree on the definition of marriage, but they do agree on one thing: a Supreme Court decision will be huge.

"It's going to have a profound impact on how people define marriage," said Eva Andrade, with Hawaii Family Forum.

Unlike same-sex supporters more visual and vocal demonstration, Hawaii Family Forum and others opposed are taking a much quieter approach to the cases before the Supreme Court.

"We're asking people to unify and pray for the decision by the justices and for family in the community. What will happen in the next few days is important," said Andrade.

Because of the cases before the high court, Hawaii's lawsuits on same-sex marriage are on hold.
